One Ready citation from Raising the Bar, PDF sheet 15. The claim is a practitioner design principle and needs independent corroboration before promotion.
A progressively stocked home bar can increase recipe coverage and learning value by favoring bottles and prepared ingredients that support several drinks while reusing items already in the collection.
Multi-use should be assessed against the intended repertoire, audience, budget, storage, and historical goals. A specialized bottle may be justified even if it unlocks only one high-priority drink.
Adams and Grier explicitly exclude single-use ingredients and organize the book so that each acquisition compounds the usefulness of earlier purchases. This supports a practical coverage-maximization principle, but the evidence is one experienced practitioner source rather than a comparative study.
Created after complete 525-sheet textual and visual review and cross-database deduplication on 2026-08-27. Retained at Researching with Weak evidence and Moderate confidence pending independent practitioner corroboration.
Assessment
The source supplies a clear operational rule: select bottles and prepared ingredients for repeated use across a growing repertoire, so each acquisition compounds the value of what is already present.
Evidence boundary
This is a practitioner method for designing a versatile home bar. It does not establish a universal optimum, and it does not make recipe count the sole measure of quality.
Drafting boundary
Use as a planning principle for the website's bottle-to-cocktail navigation and for practical home-bar guidance. Preserve exceptions for historically significant, distinctive, or deliberately specialized ingredients.
